Ok, I'm a beginner so forgive me if this is a dumb question. I started a project today making a lap blanket. I'm knitting on 29" circular needles and the row is 137 sts across. Here's my dilemma...I cast on 137 sts, I knitted across the first row and had 137 sts, then I knitted across the 2nd row and ended up with 138 sts!! I looked back through my work and nothing looks out of place. Here's my question...do I have to tear out that entire row and start over, or is there someway to fix it, like k2 tog on the first st of the 3rd row? How frustrating!! :?? Thanks for your help!
